Der Widerstand für die Kurzsehlussströme kann weiter dadurch vergrössert werden, dass, wie in Fig. 2 gezeigt, zwischen die Bürste b und das Druckstück d ein Zwischenstück eingefügt wird, das

stellen, wodurch die Stärke dieser Ströme noch weiter herabgedrückt wird. Das Druckstück und das Zwischenstück können auch miteinander zusammengesetzt werden, wobei das Druekstück als Kappe für das Zwischenstück dient. Der Widerstand für die Kurzschlussströme ist dann zwar nicht so gross wie bei getrenntem Zwischenstück und Druckstück, ist aber doch noch grösser als bei Verwendung eines einfachen massiven metallischen Druckstücks.

können, ist der Bürstenkasten h mit einer Isolationsschicht n ausgekleidet.
Statt dessen kann auch die Bürste an ihren Seiten mit einer Isolationsschicht umhüllt werden.
Das in Fig. 2 dargestellte Druckstück besitzt Querschlitze e, durch die es selbstfedernd wird.
Dadurch wird eine besonders gute Auflage auf den leitenden Schichten der Bürste gesichert.
Die Verwendung des leitenden Druekstückes hat auch noch den besonderen Vorteil, dass die leitenden Schichten der Bürste sehr dünn gehalten werden können, ohne dass Schwierigkeiten für die Befestigung von Ableitungen entstehen.
PATENT-ANSPRÜCHE :
1. Stromabnehmer für Stromwender mit in der Umfangsrichtung des Stromwenders unterteilter, von Isolationssehiehten durchzogener Bürste und Widerständen zwischen den Bürstenteilen und dem gemeinsamen Stromableiter, dadurch gekennzeichnet, dass die Widerstände durch Übergangswiderstände zwischen den Endflächen der Bürstenteile und einem auf den Endflächen frei aufliegenden gemeinsamen
EMI2.3
verbunden ist.

The resistance for the short-circuit currents can be further increased in that, as shown in FIG. 2, an intermediate piece is inserted between the brush b and the pressure piece d

place, whereby the strength of these currents is further depressed. The pressure piece and the intermediate piece can also be put together with one another, the pressure piece serving as a cap for the intermediate piece. The resistance for the short-circuit currents is then not as great as with a separate intermediate piece and pressure piece, but it is still greater than when using a simple solid metallic pressure piece.

can, the brush box h is lined with an insulation layer n.
Instead, the sides of the brush can also be covered with an insulation layer.
The pressure piece shown in Fig. 2 has transverse slots e, through which it is self-resilient.
This ensures particularly good support on the conductive layers of the brush.
The use of the conductive pressure piece also has the particular advantage that the conductive layers of the brush can be kept very thin without creating difficulties for the attachment of leads.
PATENT CLAIMS:
1. Current collector for commutator with divided in the circumferential direction of the commutator, traversed by Isolationssehten brush and resistors between the brush parts and the common current conductor, characterized in that the resistors by contact resistances between the end faces of the brush parts and a joint freely resting on the end faces
EMI2.3
connected is.
